matlab problem, help me experts plz

aabbddlah

Hello everyone

i v just joined the forum and i would like u to give me some sort of help in my induction motor project
i am using matlab to carry out the value for torque and then plot the torque Vs speed graph using matlab

so torque should be calculated for different speeds and slips
(Not only different values of speed!)
So
given the following parameters

R2=.8ohm
Rt=1.2ohm
Lt=2.2ohm
L2=3 ohm
v=225v
s = (ws-wr) / ws , where ws=synchronous speed and wr=rotor speed
i2= as in attachment

torque=(3./wr)*(I2^2)*(R2/s)*(1-s)

Also current cannot be one constant value
It should be calculated accordingly to slip values, so for each slip value we should have a value for current
To sum up , I think that we should use for loop to carry out values of slip ,corresponding speed ,and corresponding current on a range of values to create the proper plot
If the code is correct we must end up with the graph shown in the attachment
I will be thankful if u would help me
Many thanks<!-- google_ad_section_end -->
